Bug Description
Any operation that probes stuff over XRANDR is really slow. Running just "xrandr" takes slightly less than 4 seconds. A bit of experimentation reveals that adding:
Section "Monitor"
Identifier "HDMI1"
Option "Ignore" "True"
EndSection
...to xorg.conf fixes it. I have no HDMI ports at all, so this is not a problem.
Only HDMI1 seems to be the problem.

Kernel should probably be quirked for this laptop to not provide an HDMI1 since it doesn't exist. Adding task for kernel team.
